已经解决了，谢谢老师

为什么composer.json里面没有看见laravelcollective这个扩展，还有我没有安装illuminate/html这个扩展，我是新用composer下载的laravel5.3

D:\WWW>composer require laravelcollective/html 5.4.*
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Package illuminate/html is abandoned, you should avoid using it. Use laravelcollective/html instead.
Writing lock file
Generating autoload files

老师这个也没有报错，为什么没有安装上，该怎么办？laravel5.3

不好意思，对不起，麻烦你了

http://socket.io/docs/ 好网站

总之，谢谢老师，终于解决了。原来是node.js未重启

socket.io-1.4.5.js:1 GET http://192.168.1.103:3000/socket.io/?EIO=3&transport=polling&t=LcNr4ov 404 (Not Found)

http://192.168.1.103:3000/socket.io/?EIO=3&transport=polling&t=LcNr3aX Failed to load resource: the server responded with a status of 404 (Not Found)

我也不清楚，但是还是感谢老师耐心帮忙

可以正常跑起来，换成127.0.0.1也不行
